Abstract

Objective: To explore the predictive value of white blood cell count/mean platelet volume WMR in short-term prognosis and the risk factors in children with acute attack of bronchial asthma BA.Methods: 94 children with acute attack of BA and 52 healthy children controls with matched age were enrolled as the study group and the control group between June 2022 and December 2023 respectively. The levels of white blood cell count WBC), mean platelet volume MPV and WMR were compared between the two groups. According to disease severity children in the study group were divided into mild group moderate group and severe group. The clinical data laboratory indexes and WMR level of patients in the three groups were compared. According to short-term prognosis the patients were divided into the good prognosis group and the poor prognosis group. The clinical data laboratory indexes and WMR revels in the two groups were compared. The predictive value of WMR for short-term prognosis was analyzed by receiver operating characteristic ROC curves and risk factors of short-term prognosis were analyzed by multivariate Logistic regression analysis.Results: The levels of serum WBC MPV and WMR in the study group were higher than those in the control group P<0.05), and these indicators were higher in the severe group than in the moderate group and the mild group P<0.05. There were significant differences in allergy history history of repeated respiratory tract infection and WMR level between the poor prognosis group and the good prognosis group P<0.05. ROC curves analysis showed that AUC 95%CI specificity and sensitivity of WMR for predicting short-term prognosis of BA children were 0.721 0.619-0.809 60.27% and 76.19% respectively. Binary Logistic regression analysis showed that allergy history OR=5.484P=0.006), history of repeated respiratory tract infection OR=5.695P=0.015 and WMR >0.93 OR=4.053P=0.022 were independent risk factors of short-term prognosis in children with acute attack of BA P<0.05.Conclusion: The level of serum WMR increases in children with acute attack of BA. It is correlated with disease severity and has certain predictive value for short-term prognosis.
